The Proteome 1.2 Flashcards
1
Q
what is the proteome?
A
entire set of proteins expressed by a genome
2
Q
why is the proteome larger than the number of genes?
A
because more than one protein can be produced from a single gene as a result of alternative RNA splicing
3
Q
what is the genome?
A
total genetic material in a cell
4
Q
what are genes that do not code for proteins called?
A
non-coding RNA genes
5
Q
what do genes that are transcribed produce?
A
tRNA, rRNA and RNA molecules that control the expression of other genes
6
Q
what factors affect protein expression?
A
- metabolic activity of the cell
- cellular stress
- response to signalling molecules
- diseased vs healthy cells
